#kinematics equations

[idontmindifuforgetme]

This whole situation is so disgusting. You poor thing! Glad you can see the humour in it

Lol I’m lowkey bummed out but thank you😭😭 that’s literally every guy my age what can u do. But I also think he’s having a quarter life crisis like when we were studying he was using a physics mcat book that dates back to 2003 for no fucking reason I was like what is this man doing he’s so lost

[supersymmetries]

i've finally reached the part in the semester where we're covering the second law of thermodynamics. matt bellamy we're in it together now

[spursthatjinglejanglejingle]

I'm cooked for my physics exam but it's okay because everyone in the class I've talked to is also cooked, we're cooked together 💕

Mario throws a brick in a vacuum on Earth; it is unaffected by air resistance and has a constant downward acceleration of 9.81 m/s². When the brick leaves his hand exactly 1 meter above the ground level, it is traveling a whopping 100 m/s at an angle of 30° above the horizontal.

How far away from its initial position will the brick hit the ground?

[oflgtfol]

i do have to say though he is so fun to talk to especially bc we are both the same brand of nerds ie. sci-fi movies and like astronomy/science in general. he’s an astronomer more in the earth/planetary sciences kind of way whereas i have a much heavier background in the physics side of astro and so like i get to talk to him about science, have him ACTUALLY LISTEN AND UNDERSTAND AND BE INTERESTED, while also still not having a 1:1 similarity in our knowledge. like he never took optics and he doesnt wear glasses so i was explaining to him how im legally blind without mine and like how short my near point is as opposed to his etc. like nobody else in my life is interested in this shit except for the people who i already took classes with and therefore already knows about it

LESSON PLAN

studying isn’t so entertaining when you have something else on your mind - something that involves your shy tutor. inspired by this request

contains: loss of virginity (don’t read if uncomfortable)

hamzah always knocks on your door too lightly, shifting from foot to foot like he’s thinking about running away. you open the door and he’s standing there with his sleeves tugged down over his hands, backpack hung on his shoulders.

“hi,” he mumbles, not meeting your eyes.

“you’re late,” you say, but you’re smiling, leaning against the doorframe in a tank top that’s showing too much. or not enough, depending how you look at it.

“sorry - uh, my car.. i mean- yeah. sorry.”

you step aside to let him in, and he walks in like he’s entering a museum. eyes darting around your room - pink sheets, candles, glossy lip balm tubes scattered on the desk - like he doesn’t know where he’s allowed to look. his cheeks are already turning pink.

“you can sit,” you say, already flopping onto your bed.

he hesitates. “uh- here?”

“yeah, hamzah,” you grin, patting your bedspread. “you’re not gonna, like, catch cooties. i’m tired of you always sitting at my desk all the time. you’re too far away.”

he laughs, but it’s nervous. he sinks down onto the very edge of the mattress, leaving a prominent gap of space between you two. he opens the cover of his textbook, flipping through pages with shaky hands. he clears his throat.

“so.. i figured we could start with the practice on page 211. if that’s okay.”

you hum. “sure.”

you lean over to look at the page. and when you do, your arm brushes his. his breath catches. he tries not to move, but he tries even harder not to look at the way your collarbone is peeking out or how your lip gloss shines.

you glance at him. he looks like he’s trying to remember how to breathe.

“you okay?”

“y-yeah. yep. page 211.”

he’s trying so hard.

his voice is all quiet and focused, like he really believes you’re going to care about vectors and kinematic equations just because he’s reading them off a flashcard.

“so, um, if the object’s moving with constant acceleration, you can use the formula - i mean, like.. initial velocity plus acceleration times time is..”

he squints down at his notes and pushes his glasses up with the side of his hand.

the frames keep sliding down his nose. you want to tug them off and crawl into his lap.

you’re sprawled out on the bed in your tiny sleep shorts, legs stretched long and bare toward him, like you’re just testing the waters - seeing how far you can push him before something breaks.

he’s still perched right on the edge of the mattress, like your bed is a sacred place. like one wrong move might make him bolt from the room.

“hamzah,” you hum, voice sugar-sweet and full of amusement.

his eyes dart up, nervous and wide behind his lenses. “yeah?”

you tilt your head, playing with the strap of your top. “you’re so cute when you talk about physics.”

he blinks. you see the pink rise to his cheeks.

“i- uh, thanks. it’s, um.. it’s just the way the curriculum explains it, i’m not, like, making it up or anything-”

you smile. “i know. you’re just so smart.”

his voice stutters into silence. his fingers tighten around the flashcard.

you roll onto your stomach, bending your knees up and swinging your feet lazily. “are you always this nervous around girls?”

“i’m not - i’m not nervous,” he says too fast, eyes flitting around the room like they’re begging for a safe place to land. “i just, uh, wanna make sure you understand it. the material. so you don’t fail.”

you giggle. “oh, right. i stopped listening, like, fifteen minutes ago.” your voice softens into a pout. “i’m bored.”

he hears that tone in your voice and looks up at you, the flashcard in his hand starting to tremble a little.

“b-bored?”

you nod, stretching again, letting your shorts ride up just a bit more. “mhm. think you could teach me something else?”

he swallows. audibly. “i- i don’t know what else you’d want me to teach you..”

you sit up on your knees and shift closer, slow and casual, like this isn’t going to break his entire understanding of reality.

“well,” you murmur, touching the hem of his sleeve. “you know what i heard?”

“what?” he nearly whispers.

“i heard that you’ve never kissed a girl before.”

he doesn’t say anything. he doesn’t even try to deny it. his mouth opens like he wants to speak, but nothing comes out.

you hum, pleased. “you want to?”

his whole body tenses. “i.. y-you mean.. right now?”

you reach up and adjust his crooked glasses, nodding. “right now.”

his eyes flick to your mouth and back up again. “y-yeah. if.. if you want to.”

you laugh softly and cup his cheek with one hand.

he melts.

he makes a tiny, broken noise in the back of his throat like that short-circuited something in his brain.

you kiss him.

he gasps against your mouth - not dramatic, just genuinely surprised. he doesn’t know where to put his hands, he doesn’t even move at all until you guide him, fingers lacing with his and placing them on your hips.

his mouth is soft, warm, clumsy. he kisses like he’s afraid to mess it up, like he’s thinking too hard about what to do with it. his lips are glossy and red when you finally pull back.

he blinks up at you like he’s not sure the kiss actually happened. like maybe he blacked out halfway through it. his glasses are crooked again. you fix them for him gently.

“you wanna learn something?” you whisper.

he nods, like it’s instinct.

“lie back. i’ll show you how to make a girl feel good.”

he obeys. no questions asked.

and you’re already thinking about how he’s going to look between your thighs - desperate, overwhelmed, ready to worship you without even knowing how.

he lies back, palms flat against your sheets. his fingers are twitching like he doesn’t know what to do with them, and his legs are a little too close together, stiff with nerves. his shirt rides up at the hem and his glasses are fogging slightly, but he watches you as you crawl over him and straddle his waist like you’ve already done this a hundred times.

he looks terrified.

yet already, he’s so hard.

you lean down, kiss his flushed cheek, whisper against his ear, “you wanna go down on me?”

his breath catches. “i- i’ve never..”

“i know.”

you smile and kiss him again, slower this time. “i’ll help you.”

and that’s all it takes. he nods, frantic, already trying to sit up like he wants to be useful.

you tug your shorts down slow, teasing, watching the way his eyes track every inch of your skin. when you toss your panties aside, his mouth drops open like he’s seeing something heavenly.

you climb up and settle your thighs over his face, one knee on either side of his head. “you okay down there?” you ask sweetly.

he breathes out hard, nodding. “yeah. yeah, i’m- fuck.”

you giggle.

and then you lower yourself.

his first lick is so clumsy it barely even lands. he sort of just presses his tongue to you like he’s not sure what he’s supposed to do, and it’s so messy, so warm, so desperate it makes you laugh breathlessly.

“oh my god,” you whisper, grinding down just a little. “you really have no idea what you’re doing, hamzah.”

he moans into you. it vibrates through your whole body.

“but you want to, don’t you?”

he nods under you. you feel it. his hands are on your thighs now, squeezing gently, trying to hold you in place even though you’re the one doing all the moving.

“don’t think too hard about it,” you murmur. “just try.”

and he does.

he’s sloppy and starved and so completely in awe of your body. he licks too fast, then too slow, then gets better when you tug on his hair and grind your hips just right.

he’s not coordinated, but he’s willing.

you rock against his face, moaning when his tongue finally catches your clit the way you want it to.

“fuck - right there, hamzah. keep going, don’t stop.”

he whimpers, like the praise is feeding him more than your cunt is. you ride it out, guiding his head, rolling your hips while he holds on and tries so hard to avoid screwing it up.

he’s soaked. his chin, his nose, his whole mouth - all wet. all yours.

when you finally cum, it’s sharp and fast and mean, your fingers yanking his hair and your thighs trembling around his head.

you don’t even get all the way off him. you just slide down until you’re sitting on his chest, catching your breath, looking down at him.

his mouth is red and slick and his lips are parted. he looks ruined. you smile, feeling proud.

“good boy,” you whisper.

he twitches under you - hips jerking up like he’s this close from just finishing in his pants.

his hands hover in the air like he doesn’t know where to put them. not on your waist, not on your hips, not on your thighs. you take them and pin them to the bed.

“stay still,” you tease, climbing down his body. “i’m not done with you yet.”

his eyes flutter shut for a second, overwhelmed. he’s so red in the face you can see it creeping down his neck, blooming along his skin like heatstroke.

“you’ve never even.. touched a girl before, have you?”

he shakes his head. swallows hard. “n-no. i mean, not - not like this.”

you hum like you’re thinking. “not even.. over-the-clothes stuff?”

“no,” he breathes. “i’ve only ever - like.. y’know. on my own.”

you sit back and smile like you’re delighted. “god, that’s so cute.”

he groans, burying his face in his arm. “please don’t make fun of me.”

“hamzah,” you purr, leaning in to kiss the corner of his mouth, “i’m not making fun of you. i love it.”

his hips twitch at that. he doesn’t even mean to - it’s just instinct, pure and helpless.

you reach down and finally palm him over his sweats. he’s rock hard, twitching, so sensitive. he gasps, trying to hold still.

“look at you,” you murmur. “all worked up and i haven’t even taken these off yet.”

he covers his face again. “i’m sorry-”

you laugh sweetly. “don’t be sorry, hamzah. you’re doing perfect.”

your fingers curl into the waistband of his sweats. you pull them down slow, along with his boxers, and he lifts his hips eagerly without you even asking.

and when he springs free - flushed and leaking and pretty - you just look at him for a second.

“fuck,” you whisper. “you’ve been keeping this from me?”

his face is burning. “i didn’t - m’sorry, i didn’t think-”

you cut him off with a kiss.

“you want me to be your first, don’t you?” you exhale against his lips.

he nods instantly. “please. i want it so bad.”

“yeah?” you stroke him once, slow and mean. he chokes on a moan. “you gonna be good for me?”

“yes. yes, i will, just - tell me what to do. i don’t wanna mess anything up.”

you climb back over him and straddle his hips again, dragging your slick along the length of his cock so he can feel how ready you are.

“you’re not gonna mess it up, hamzah. i’ll take care of everything.”

his whole body shudders. you reach down and guide him with one hand, pressing the head of his cock to your entrance.

“wait,” he whispers, chest rising and falling rapidly, “i don’t - i don’t wanna cum yet.”

you smile. “you’re not gonna. not yet. just breathe.”

his hands grip your waist, fingers digging in just enough to ground himself. his eyes are locked on where your bodies meet - lips parted, completely speechless.

you sink down slow. his head hits the pillow. a choked moan leaves his lips. his hips jerk without permission.

“oh - oh my god,” he whispers, voice cracking. “it’s so.. good, it’s - fuck, i’m..”

you pause halfway, hand splayed across his chest. “c’mon, breathe, hamzah.”

he gasps like he’s forgotten how.

you press a kiss to his jaw. “you’re doing so good, i promise.”

you take the rest of him inch by inch, letting him stretch you slowly. his cock is twitching inside you, like everything is too much, like he’s been waiting his whole life for this exact moment.

you settle fully, hips snug against his, and you don’t move. he’s trembling under you.

“this okay?” you ask softly, running your fingers down his chest.

he nods. “y-yeah. i just.. it’s so much. i can’t think.”

you lean down and kiss his temple. “that’s good. you think too much. you don’t have to for once.”

you rock your hips once - shallow, gentle. he gasps.

“oh my god- don’t stop-”

you shush him sweetly. his hands are fisting the sheets now. his head turns to the side like he’s trying to ground himself in anything that isn’t you, but you won’t let him look away.

you grip his chin and make him face you.

“eyes on me.”

he obeys instantly. he’s all flushed, fucked-out.

you start rocking your hips again, slow and steady, dragging yourself up and down his cock while he just whines under you.

his hands twitch at your waist, like he’s not sure if he’s allowed to touch you more, but when you grind down just right and clench around him - he loses all of that control.

his hips snap up into you without warning. once. twice. again.

“shit - i’m sorry, i didn’t mean to-”

you gasp, caught off guard by how deep he hits. your hand slaps down on his chest to keep yourself steady, but he’s already chasing it now - thrusting up into you, messy and fast and needy.

“fuck-! i can’t stop, oh god - sorry,” he whimpers.

you moan, loud. “don’t be sorry, hamzah - oh, my god.. fuck me just like that.”

his eyes go wide. his hands grip your ass, holding you down as he drives up into you with these frantic, uncoordinated thrusts.

“you feel so good - jesus, i didn’t know it would feel like this-”

you’re bouncing now, letting him fuck up into you while your fingers dig into his chest. he’s gasping under you, all choked breaths and flushed skin and eyes locked on your tits through the thin fabric of your top.

“you gonna cum already?” you tease, breathless, grinning down at him.

he nods, eyes glossy. “i’m trying not to - i swear, i’m trying.. i don’t wanna cum yet, please-”

“why not?” you pant, leaning close so your nose brushes his. “you wanna make me finish first?”

he whimpers. “yes.”

you smile. “good boy.”

and that breaks him.

he bucks up harder, sweat gathering at his temples, teeth sinking into his lip. his hands are sliding all over your waist now, greedy and clumsy like he can’t decide whether to hold you still or pull you closer.

you guide one of his hands to your clit. “touch me here, hamzah. just like i showed you.”

he does. shaky at first, then more confident when he hears how loud you moan.

and then you’re right there - hips stuttering, thighs trembling, your whole body shaking on top of him.

“hamzah, fuck- don’t stop..”

he watches you fall apart like he’s witnessing something holy.

you cry out as you cum again, clenching hard around him, and that’s when he completely unravels.

“oh fuckfuckfuck - i’m gonna cum, i can’t-”

he sobs your name as he finishes. hips locked, cock twitching, entire body stiffening under you. he moans through it, whimpering and cursing, clinging to you like you’re the only thing keeping him on earth.

his chest heaves. your body goes limp over his. and neither of you say a thing for a second - just trying to breathe. your thighs are shaking and his chest is slick with sweat, his glasses fogged and askew, but neither of you move right away.

he blinks up at the ceiling.

“oh, my god.”

you giggle against his shoulder, tucking his glasses up onto his forehead gently. “s’that good, huh?”

he just stares at you with this wrecked, teary, completely worshipful face. that’s all you need to know.

“mm. glad i could teach you something for a change.”

[dasketcherz]

people who thought varian having fellow scientists for friends was a bad idea because "it takes away his uniqueness of being one" is a pretty shallow and flat criticism

because if we're being for real, surely he is not the only scientist/alchemist that ever exists in the tangled universe, that would just be plain goofy. a group of people can indulge under the same umbrella of interest and still be distinct from each other at the same time. a great example i can think of is having a group of artist friends: fundamentally youre all good at drawing sure—but one maybe is better at rendering, one is a master at perspective, one is a pro at composition, one is a beast in color theory etc not to mention every one in the group having their own art style different from one another

the same can be said for team radical—yong is skilled in pyrotechnics and kinematics, you can count on him to estimate complicated physics. nuru is a pro in astronomy and mathematics, straight up the fastest calculator alive and the team can rely on her to make sure their equations are as accurate as possible before performing it in application. varian and hugo may both be capable of alchemy and engineering but they divide specialty on that front—varian is the better expert at alchemy and chemistry while hugo thrives at being the better mechanical engineer and thaumaturgy.

one of the endearing storyline in vat7k thats so relatable is finding your people, finding your tribe, your peers, individuals that you can connect with because of common interests. so varian having a group of people who are just like him tagging along on the road trip is a great idea. it doesnt take away his identity as a scientist, if anything, it offers so much more room for him to grow, to learn, to expand his knowledge, and to finally have people to share knowledge with.

but this is just my opinion and the former is theirs.

06.02.2025 || Day 14/100

I've been doing Kinematics for a week now, when will this end. I still have a module to finish and not enough time, and I need to stop wasting the time I have. Broke out again, didn't spiral about it but got distracted still. If I have to find out another trajectory equation or solve more vectors I might go insane so tomorrow is the last day I'll be doing this whether or not the module gets finished, sigh.

Hope everyone's having a nice day!

From Top to Bottom - Richtofen University AU

If you were a student in his class would you be able to pay attention to anything other than how hot your professor was? When Professor Richtofen notices how hot you are for teacher he confesses he's also had his eye on you, but after things get hot and heavy how do you return to being student and teacher? And what if there is more than just lust at play here?

Notes: POV swap: Reader (X) and Edward Richtofen (Primis) | both characters are switches | hurt/comfort, angst w/ a happy ending, mutual pining, smut heavy plot | This started as a one shot, but I couldn't walk away from it so it's been expanded into a full work.

Productivity Diaries (#4)

productive much, i did not sleep in the afternoon lol, and i also did smthng (scroll down) update:

maths- 1.5hr finished quadratic equations chemistry-4 hr finished redox reactions physics- solved a couple questions of kinematics

ps. i made a youtube channel , and please check it out once<3 i posted 2 videos yesterday!

[super-epic-shifty]

🐶💙: Hey Shifty, I brought Sniffles for you. HEHEHEHEHE

🩵🧪: Hey Shifty! I have a problem for you to solve:

Problem:

A delivery truck with a mass of 4500 kg is initially at rest. The driver applies the accelerator, and the truck experiences a net force of 9000 N in the forward direction.

Questions:

a) What is the acceleration of the truck?

b) After 5 seconds, what will be the velocity of the truck? (Assume the acceleration is constant)

Think about:

* Newton's Second Law of Motion: Force (F) equals mass (m) times acceleration (a) (F = ma)

* Kinematics Equation: Velocity (v) equals initial velocity (v₀) plus acceleration (a) times time (t) (v = v₀ + at)

🩵🧪: Good luck Shifty!

🐶💙: Yea. Good luck. HAHA

I AINT DOIN THATTTTTTTTT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! GET OUTTA HERE BUG BOY!!!!!!!!!!!! IDK HOWWWWWW

thanks @lonewolflupe for the tag!

Last Song: "Thought Crime" by Yorushika

Favorite Color: blue! but a dark blue like the night sky or the stratosphere

Last Book: Iron Widow by Xiran Jay Zhao; i don't think my textbooks count so this was the last book. also this was the first book i finished in years!

Last Movie: Mission: Impossible - Dead Reckoning Part One; i'm super excited for part 2 this year :D

Last Show: Doctor Who; specifically "Time of the Doctor," "The Doctor's Wife," and "Into the Dalek" though i've seen all of series 1-10 of the revived era :3

Sweet/spicy/savory: man, that's hard. i like both sweet and spicy food in moderation

Relationship status: single

Last thing I googled: "kinematic equations;" i was playing a ttrpg with my friends last night, and they wanted to know what the acceleration of something floating down a river would be given some arbitrary values for initial velocity, distance, and time. it was .225 ft/s/s btw

Current obsession: clone wars and the clones. i won't shut up about them. i love the silly little boys so much. i thought i'd find something new by now. NO! MORE CLONES!!!

I look forward to telling you: i got so many ideas kicking around. i got oc ideas sitting in sketches. i got an entire bad batch au i've been workshopping with one of my closest friends for months. there's also my overall art plans for the year. for being so inarticulate, i won't shut up XD

Time from a, r, and ω [Ex. 1]

A car decelerates at 6.6 m/s². The tires have a radius of 0.26 m and have a positive direction during the forward motion. If the initial angular velocity is 94 rad/s, how long does it take the car to fully stop?

-- Given values: -> a = 6.6 m/s² -> r = 0.26 m -> ωi = 94 rad/s -> ωf = 0 rad/s

-- Use one of the kinematic equations 1. ωf = ωi + αt 2. Δθ = ωit + (1/2)αt² 3. ωf² = ωi² + 2αΔθ

-- Use Equation 1

-- Missing α, which is angular acceleration

-- Solve for α

α = a/r α = 6.6 / 0.26 α = 25.385 rad/s²

-- Should be negative, because the car is decelerating

α = -25.385 rad/s²

-- Now solve for t using Equation 1

ωf = ωi + α 0 = 94 + (-25.385)t 0 = 94 - 25.385t -94 = -25.385t 94 = 25.385t 94 / 25.385 = t 3.7 = t

-- It takes the car 3.7 seconds to stop

Love physics, but it’s kind of a stupid subject for me. I don’t really need it for what I intend to go into in the future. Even if they didn’t have relevance to my intended field of study (which they do) I can see a point for me taking bio and chem. Knowing more than basic bio can have actual applications in your life, and it’s good to understand how bodies and cells and such work. Similar deal with chem, understanding how chemicals work will keep you from mixing cleaning products and making chemical weapons, being scared of long words you can’t pronounce in ingredient lists (oooo dihydrogen monoxide spoooookyyyyy sodium chloride terrifyingggg), a lot of things make more sense when you get chem. Physics… look. Being familiar with certain aspects can be useful. Knowing basic kinematics, comprehending acceleration and friction and that, it helps me with driving. At some level, understanding a bit about forces has practical applications. And I like the rest! I like learning, it’s cool to know how centripetal force works, how waves function, all that fun stuff. But it’s… not super useful for me to be taking the class. I feel like knowing how to use the Doppler equation to determine the speed of sound at a given temperature is not exactly crucial for someone who plans on going into palaeontology.
